My wife and I recently purchased a house with a pool that required quite a bit of work. New liner-etc.etc. However I wanted to put a timer on the pump and this is where the fun started.
The pump is a Hayward 1.5 hp superpump connected to a hard-switch box. The box has a standard 15/20 125 plug that goes to a GCFI outlet on the side of the garage. I checked the sub-panel and it is a 15a circut. The manual stated that for a 1.5hp pump I need 115/30 or 230/15 for this. I do have enough room in the box to add in a 250/15 double if need be. I was just wondering what would be the best way to set this up.
Should I got 120/30 or 250/15? also should i put a L5-30 or L6-15 outlet where the GCFI box is or just hardwire the pump? I do want a timer in the mix.
I made a few sketches to kind of show what I am thinking and what I have.
First this is the current setup

How I was considering going with a 30a outlet

Same with the 15a

or if I was gonna just hardwire to the timer. I do live in Indiana close to lake Michigan so we can get some nasty winters and would like to store some of the equipment in the garage if that is needed. (again a major noob to pools here)

Or am I going the completely wrong direction here with all of this?
thanks in advance!
